Abstract
A particulate built nonionic synthetic organic detergent composition includes a detersive proportion of a nonionic synthetic organic detergent and a building proportion, in combination, of a polyacetal carboxylate builder for the nonionic detergent and carbonate and bicarbonate builders for such nonionic detergent. Such compositions are readily made by adding polyacetal carboxylate builder to the formula of a control detergent composition, with corresponding diminutions of other component(s), and have detersive powers superior to such control despite the decrease in proportions present of detergent and other builders. Preferably, certain nonionic detergents, polyacetal carboxylate builders, carbonate and bicarbonate, in certain proportions, are employed to make a product of better detergency and physical characteristics, e.g., flowability. Processes for manufacturing the described detergent compositions are disclosed are disclosed, in which processes spray dried builder base beads, containing carbonate and bicarbonate builder salts, have nonionic detergent and polyacetal carboxylate builder mixed with or applied to them. Also described are pumpable and sprayable compositions of pol…
